[jbpm-users] [JBoss jBPM] - error while calling a bpel process

Hi, I've created a simple bpel process using the eclipse bpel designer, which contains an external web service invocation. The deployment of the bpel process to JBoss works fine. I also added the appropriate wsdl to the partner service catalog. But the following error occurs, while calling the bpel process from a servlet (using SAAJ): | ERROR [XPathEvaluator] selection of size other than one: [] | Any ideas? Thanks for help!
